STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-32604. PoCs published by ZeroPathAI.

AI-analyzed exploit summary This repository contains functional exploit code for CVE-2026-32604, demonstrating a Git clone shell injection vulnerability in Spinnaker's Clouddriver service. The PoC leverages unsanitized branch names in artifact fetch requests to achieve remote code execution.

Description

Spinnaker is an open source, multi-cloud continuous delivery platform. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, a bad actor can execute arbitrary commands very simply on the clouddriver pods. This can expose credentials, remove files, or inject resources easily. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable the gitrepo artifact types.
